Lab 12 RIP Lesson B

Objective 

• To configure RIP in a simple network.
• To check metrics and administrative distance and for RIP.
• To check load balance.
• To understand effect of topology change on RIP

Topology

Basic Setting

IPs for computers and routers have been set up.

Requirements

• You need to configure routers to use RIP to learn routing tables.
• You should use Version 2 RIP.
• You should be able to check routes based on RIP. 
• Test connectivity
• Monitor exchange of routing info based on RIP.
